Struttura di tipo migliorato per il sostegno a terra di moduli fotovoltaici e impianto fotovoltaico provvisto di questa struttura Improved type structure for ground support of photovoltaic modules and photovoltaic system provided with this structure
DESCRIZIONE DESCRIPTION
La presente invenzione concerne una struttura di tipo migliorato per il sostegno a terra di moduli fotovoltaici. L’invenzione si estende anche all’impianto fotovoltaico provvisto di questa struttura. The present invention relates to an improved type of structure for ground support of photovoltaic modules. The invention also extends to the photovoltaic system equipped with this structure.
Il campo dell’invenzione à ̈ quello delle strutture utilizzate per sostenere, a terra o su campo aperto, i pannelli solari che compongono gli impianti fotovoltaici. The field of invention is that of the structures used to support, on the ground or in the open field, the solar panels that make up the photovoltaic systems.
Le strutture di supporto attualmente note sono interamente realizzate di materiale metallico, il quale si presta in particolare a permettere di regolare l'inclinazione dei pannelli rispetto al supporto a terra. The currently known support structures are entirely made of metallic material, which lends itself in particular to allowing the inclination of the panels to be adjusted with respect to the ground support.
Tuttavia le soluzioni note ora ricordate hanno l’inconveniente che, in quanto realizzate di materiale metallico, non sono in grado di resistere all’azione corrosiva degli agenti atmosferici, con la contemporanea presenza delle correnti vaganti, a loro volta dovute al funzionamento stesso deirimpianto. However, the known solutions just mentioned have the drawback that, as they are made of metallic material, they are not able to resist the corrosive action of atmospheric agents, with the simultaneous presence of stray currents, in turn due to the operation itself. of the plant.
I fenomeni corrosivi sono soprattutto marcati in corrispondenza del colletto dei pali interrati, che costituiscono la base della struttura di sostegno. A loro volta le correnti vaganti lungo l’intera struttura metallica dell’impianto estendono i fenomeni corrosivi anche alla parte interrata dei pali, nonché alle sezioni di appoggio dei pannelli alla struttura stessa. Corrosive phenomena are especially marked in correspondence with the collar of the buried poles, which form the basis of the support structure. In turn, the stray currents along the entire metal structure of the plant extend the corrosive phenomena also to the underground part of the poles, as well as to the support sections of the panels to the structure itself.
Un ulteriore inconveniente delle note strutture metalliche di sostegno degli impianti fotovoltaici à ̈ inoltre rappresentato dalla loro leggerezza, che rende il sistema particolarmente instabile all’azione del vento e di altre sollecitazioni meccaniche, per esempio dovute alle forti piogge, alla caduta di neve e simili. A further drawback of the known metal supporting structures of photovoltaic systems is also represented by their lightness, which makes the system particularly unstable to the action of wind and other mechanical stresses, for example due to heavy rains, snow fall and similar.
Costituisce lo scopo principale della presente invenzione quello di fornire una nuova struttura per il sostegno a terra di moduli fotovoltaici che, in rapporto a quelle attualmente note, permetta di superare i problemi legati alla formazione ed alla trasmissione delle correnti vaganti lungo la medesima struttura, così da eliminare o da ridurre in modo drastico la formazione di parti arrugginite, responsabili di pericolose rotture sull'impianto. The main purpose of the present invention is to provide a new structure for the ground support of photovoltaic modules which, in relation to those currently known, allows to overcome the problems related to the formation and transmission of stray currents along the same structure, thus ¬ to eliminate or drastically reduce the formation of rusty parts, responsible for dangerous breakages on the system.
Un ulteriore scopo dell'invenzione à ̈ quello di fornire una struttura del tipo anzidetto, che sia più stabile alle sollecitazioni meccaniche esterne in rapporto alle analoghe strutture di tipo tradizionale. A further object of the invention is to provide a structure of the aforesaid type, which is more stable to external mechanical stresses in relation to similar structures of the traditional type.
La presente invenzione ha anche lo scopo di offrire una nuova struttura di sostegno a terra di moduli fotovoltaici che, diversamente da quelle attualmente conosciute, sia realizzata con materiali meno costosi e tuttavia in grado di offrire capacità di resistenza, almeno uguali a quelle degli analoghi sistemi della tecnica nota. The present invention also has the purpose of offering a new ground support structure for photovoltaic modules which, unlike those currently known, is made with less expensive materials and yet capable of offering resistance capacity, at least equal to those of similar systems. of the known art.
Questi ed altri scopi sono raggiunti con la struttura e l'impianto delle rivendicazioni rispettivamente 1 e 14. Dei preferiti modi di realizzare l’invenzione risultano dalle restanti rivendicazioni. These and other objects are achieved with the structure and system of claims 1 and 14, respectively. Preferred ways of carrying out the invention result from the remaining claims.
In rapporto alle note strutture per il sostegno a terra di moduli fotovoltaici, quella secondo l’invenzione offre il vantaggio di isolare la parte elettrica dell'impianto, costituita dai pannelli fotovoltaici, rispetto al terreno che sostiene la struttura. In questo modo si evita la creazione di correnti vaganti e, con esse, anche la formazione di indebolimenti strutturali in corrispondenza di pericolose formazioni di ruggine sulla struttura stessa. In relation to the known structures for ground support of photovoltaic modules, the one according to the invention offers the advantage of isolating the electrical part of the system, consisting of the photovoltaic panels, from the ground that supports the structure. In this way, the creation of stray currents is avoided and, with them, also the formation of structural weakening in correspondence with dangerous rust formations on the structure itself.
Un ulteriore vantaggio della struttura dell’invenzione à ̈ rappresentato dalla migliorata stabilità offerta da questa, grazie all'elevato peso specifico del cemento di costituzione sia dei pali interrati, sia delle traverse superiori. A further advantage of the structure of the invention is represented by the improved stability offered by this, thanks to the high specific weight of the concrete constituting both the underground poles and the upper crosspieces.
A questi vantaggi, la struttura dell’invenzione aggiunge anche il minor costo della stessa, conseguente all'uso del cemento come materiale per la sua realizzazione. To these advantages, the structure of the invention also adds the lower cost of the same, resulting from the use of cement as a material for its realization.
Questi ed altri scopi, vantaggi e caratteristiche risultano dalla descrizione che segue di un preferito modo di realizzare la struttura e rimpianto dell’invenzione illustrati, a titolo di esempio non limitativo, nelle figure delle allegate tavole di disegni. These and other objects, advantages and characteristics result from the following description of a preferred way of realizing the structure and regret of the invention illustrated, by way of non-limiting example, in the figures of the attached drawings.

L’impianto fotovoltaico dell’invenzione à ̈ indicato complessivamente con 1 in figura 1. Questo à ̈ composto da una pluralità di pannelli o moduli fotovoltaici 2, a loro volta supportati da una struttura 3 per il sostegno degli stessi sul terreno 4. The photovoltaic system of the invention is indicated as a whole with 1 in figure 1. This is composed of a plurality of photovoltaic panels or modules 2, in turn supported by a structure 3 for supporting them on the ground 4.
Come meglio à ̈ illustrato in figura 2 la citata struttura di sostegno 3 à ̈ composta da una pluralità di pali 5 realizzati di cemento, preferibilmente di cemento armato precompresso, e piantati nel terreno 4 fino ad una profondità sufficiente alla stabilità dell’impianto. Su questi pali 5 sono inoltre vincolate, con orientamento regolabile per mezzo di un opportuno snodo 7, delle traverse 6, anch’esse realizzate con lo stesso materiale di fabbricazione dei pali 5. Trasversalmente alle citate traverse 7 sono infine fissati dei correnti 8 di materiale metallico, sui quali si appoggiano i pannelli 2. As best illustrated in figure 2, the aforementioned support structure 3 is composed of a plurality of poles 5 made of concrete, preferably of prestressed reinforced concrete, and planted in the ground 4 up to a depth sufficient for the stability of the system. On these poles 5 are also constrained, with adjustable orientation by means of a suitable joint 7, of the crosspieces 6, also made with the same manufacturing material of the poles 5. metal material, on which the panels rest 2.
Dalla descrizione che à ̈ stata ora fornita si comprende come il materiale di formazione dei pali 5 e delle traverse 6 in cemento armato precompresso isoli i pannelli fotovoltaici 2 dal terreno 4. Questo ha il vantaggio di inibire la formazione di correnti vaganti lungo la struttura di sostegno 3 e, quindi, di ostacolare la creazione di ruggine che possa indebolire o ridurre le capacità portanti della medesima struttura 3. From the description that has now been provided it can be understood how the material forming the poles 5 and crossbeams 6 in prestressed concrete isolates the photovoltaic panels 2 from the ground 4. This has the advantage of inhibiting the formation of stray currents along the structure of support 3 and, therefore, to hinder the creation of rust that can weaken or reduce the bearing capacity of the same structure 3.
Nella variante di figura 5, ciascuna traversa 6 in cemento della struttura di sostegno 3 à ̈ sorretta da due pali 5, anch’essi di cemento, provvisti di attacco inclinabile sui rispettivi snodi 7. In questa variante la presenza degli snodi 7 permette di scegliere l'inclinazione delle traverse 6 rispetto ai pali 5, al momento di assemblare la struttura di sostegno 3. In the variant of figure 5, each crosspiece 6 in concrete of the support structure 3 is supported by two poles 5, also made of concrete, provided with a tilting attachment on the respective joints 7. In this variant the presence of the joints 7 allows to choose the inclination of the crosspieces 6 with respect to the poles 5, when assembling the support structure 3.
Lo snodo 7 di collegamento ad inclinazione variabile del palo di cemento 5 sulla traversa di cemento 6, meglio rappresentato in figura 6, comprende una staffa 9 di attacco sulla testa del corrispondente palo 5 ed un supporto 10 di attacco alla rispettiva traversa 6, entrambi aventi conformazione sostanzialmente ad “U†. Il medesimo supporto 10 à ̈ a sua volta incernierato alla staffa 9 in corrispondenza di alette 11 associate alla medesima staffa 9, nonché di alette 12 fissate al citato supporto 10 (figure 8 e 9). Le medesime alette 11 , in numero di due sulla staffa 9, sono provviste di un foro 13 e di un’asola ad arco di cerchio 14 (figura 10). Analoghi fori 15 e 16 sono presenti sulle corrispondenti alette 12 del supporto 10 (figura 8). L'oscillazione di queste alette 12 sulle alette 11 della staffa 9 à ̈ quindi realizzata per rotazione attorno ad un perno 17, a sua volta disposto all'interno dei citati fori 13 e 16 (figura 7). The joint 7 for connection with variable inclination of the concrete pole 5 on the concrete crosspiece 6, better represented in figure 6, comprises a bracket 9 for attachment to the head of the corresponding pole 5 and a support 10 for attachment to the respective crosspiece 6, both having substantially â € œUâ € conformation. The same support 10 is in turn hinged to the bracket 9 in correspondence with fins 11 associated with the same bracket 9, as well as fins 12 fixed to the aforementioned support 10 (Figures 8 and 9). The same fins 11, two in number on the bracket 9, are provided with a hole 13 and a circular arc slot 14 (Figure 10). Similar holes 15 and 16 are present on the corresponding fins 12 of the support 10 (Figure 8). The oscillation of these fins 12 on the fins 11 of the bracket 9 is therefore achieved by rotation around a pin 17, in turn arranged inside the aforementioned holes 13 and 16 (Figure 7).
Il controllo e l’ampiezza della rotazione tra queste parti sono forniti da un perno 18, alloggiato nel foro 15 delle alette 12 e nell’asola 14 delle alette 11. Vantaggiosamente i citati perni 17 e 18 sono dotati di teste filettate, che permettono di fissare l’angolo di inclinazione dello snodo per mezzo di bulloni. The control and the amplitude of the rotation between these parts are provided by a pin 18, housed in the hole 15 of the fins 12 and in the slot 14 of the fins 11. Advantageously, the aforementioned pins 17 and 18 are equipped with threaded heads, which allow to fix the angle of inclination of the joint by means of bolts.
Di preferenza sia la staffa 9, sia il supporto 10 dello snodo 7 sono provvisti di aperture laterali 19, con pareti 20 svasate verso l’interno, ovvero nella direzione del palo 5 e della traversa 6, così da favorire la presa o l'aggrappaggio delle citate parti dello snodo sul cemento di costituzione del detto palo e della detta traversa. Preferably both the bracket 9 and the support 10 of the joint 7 are provided with lateral openings 19, with walls 20 flared towards the inside, that is in the direction of the pole 5 and of the crosspiece 6, so as to facilitate the grip or the clinging of the aforementioned parts of the joint on the concrete constituting the said pole and the said crosspiece.
II serraggio sia della staffa 9 alla testa del palo 5, sia del supporto 10 sul corpo della traversa 6, à ̈ infine completato per mezzo di viti 21, alloggiate entro corrispondenti fori 22 ricavati sulle appendici sporgenti 23 delle staffe 9 e del supporto 10, entrambi sagomati sostanzialmente ad “U†(figure 6,8 e 10) The tightening of both the bracket 9 to the head of the pole 5 and of the support 10 on the body of the crosspiece 6 is finally completed by means of screws 21, housed in corresponding holes 22 obtained on the protruding appendages 23 of the brackets 9 and of the support 10, both substantially shaped to â € œUâ € (figures 6,8 and 10)
Nella variante di figura 11 lo snodo tra il palo 5 e la traversa 6 integra la staffa 9 con un diverso supporto alla traversa 6, formato da una piastra 24 e da fascette 25, a loro volta provviste di linguette risvoltate 26 alloggiate ad incastro entro corrispondenti fessure 27 ricavate sulla medesima piastra 24. In the variant of figure 11 the joint between the pole 5 and the crosspiece 6 integrates the bracket 9 with a different support to the crosspiece 6, formed by a plate 24 and by bands 25, in turn provided with folded tongues 26 housed interlocking within corresponding slots 27 obtained on the same plate 24.
II fissaggio definitivo delle fascette 25 sulla piastra 24, così da bloccare la traversa 6, à ̈ realizzato per mezzo di viti (non illustrate) alloggiate entro il foro 28 della rispettiva linguetta 26 ed in corrispondenza del foro (non illustrato) presente sulla piastra 24. The final fixing of the clamps 25 on the plate 24, so as to lock the crosspiece 6, is made by means of screws (not shown) housed in the hole 28 of the respective tab 26 and in correspondence with the hole (not shown) on the plate. 24.
Nella variante di figura 12, l’ancoraggio della traversa 6 di cemento alla piastra 24 à ̈ realizzato per mezzo di tiranti flessibili 29, eventualmente con integrazione di una piastra di rinforzo 30. In the variant of figure 12, the anchoring of the concrete crosspiece 6 to the plate 24 is achieved by means of flexible tie rods 29, possibly with the integration of a reinforcing plate 30.
Il corrente 8 di figura 13 possiede anch’esso una conformazione sostanzialmente ad “U†, provvista di alette laterali 31 risvoltate verso l’esterno e adatte per l’appoggio alla corrispondente traversa 6. La parte superiore 32 del corrente 8 à ̈ invece quella che supporta il pannello 2. Vantaggiosamente i correnti 8 sono realizzati di materiale metallico, di preferenza alluminio. L’ancoraggio dei correnti 8 alle traverse 6 à ̈ inoltre vantaggiosamente realizzato per mezzo dei citati tiranti flessibili 29. The batten 8 in figure 13 also has a substantially U-shaped conformation, provided with lateral fins 31 turned outwards and suitable for supporting the corresponding crosspiece 6. The upper part 32 of the batten 8 It is instead the one that supports the panel 2. Advantageously, the beams 8 are made of metallic material, preferably aluminum. The anchoring of the beams 8 to the crosspieces 6 is also advantageously carried out by means of the aforementioned flexible tie rods 29.
All’invenzione, come sopra descritta ed illustrata, à ̈ possibile apportare delle modifiche per realizzare delle varianti, comunque comprese nell’ambito delle rivendicazioni che seguono. Così, per esempio, la struttura di sostegno 3 potrebbe comprendere delle traverse 6 di materiale diverso del cemento armato precompresso, quest’ultimo restando tuttavia il materiale di costituzione dei pali 5. To the invention, as described and illustrated above, it is possible to make modifications to realize variants, however included in the scope of the following claims. Thus, for example, the support structure 3 could comprise crosspieces 6 made of a different material than the prestressed concrete, the latter remaining however the material for the construction of the poles 5.
